How do you find the area of an obtuse triangle?
Area of an obtuse angle triangle = ½ * b * h , where b is the base and h is the height of the triangle.
What is the rule for obtuse triangle?
The sum of the interior angles of the obtuse triangle is equal to 180 degrees only. This means the angle sum property for any triangle remains the same. Thus, if one angle is obtuse or more than 90 degrees, then the other two angles are definitely acute or both the angles are less than 90 degrees.
How do you calculate obtuse?
You can calculate an obtuse triangle using the lengths of the triangle’s sides. Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4.
What do obtuse triangles look like?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.
How many altitudes can a obtuse triangle have?
three altitudes
Every triangle has three altitudes. For an obtuse triangle, at least one of the altitudes will be outside of the triangle, as shown in the picture at the beginning of this section.
How do you solve an obtuse angle?
To find if a triangle is obtuse, we can look at the angles mentioned. If one angle is greater than 90° and the other two angles are lesser along with their sum being lesser than 90°, we can say that the triangle is an obtuse triangle. For example, ΔABC has these angle measures ∠A = 120°, ∠A = 40°, ∠A = 20°.
What is an example of an obtuse angle?
Examples of Obtuse Angles We know that angles measuring greater than 90° and less than 180° are called obtuse angles. Therefore, angles that measure 145°,150°,178°,149°, 91° are considered as obtuse angle examples.
What is the formula for an obtuse angle?
An obtuse triangle is any triangle that contains an obtuse angle — an angle that is greater than 90 degrees. The formula for finding the area of an obtuse triangle is the same as for other triangles, area = 1/2 x (base x height).
How do you find the angle of an obtuse triangle?
Since every triangle has a measurement of 180 degrees, a triangle can only have one obtuse angle. You can calculate an obtuse triangle using the lengths of the triangle’s sides. Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together.
How do you calculate a triangle?
Triangle area formula. A triangle is one of the most basic shapes in geometry. The best known and the simplest formula, which almost everybody remembers from school is: area = 0.5 * b * h, where b is the length of the base of the triangle, and h is the height/altitude of the triangle.
What is an obtuse angle?
In Mathematics, “an obtuse angle is an angle which is greater than 90° and less than 180°”. In other words, an obtuse angle is between a right angle and a straight angle. Let us consider the below example, From the figure, it is noted that the smaller angle is called the obtuse angle, and the larger angle formed is called the reflex angle.
